The Seattle Mariners have the opportunity to end the first half of the season on a positive note on Sunday, although it'll end with them being a few games under .500.
Oakland's Ryon Healy, the ex-Oregon Duck, doubled home the eventual winning run off closer Edwin Diaz in the top of the ninth inning as the Athletics beat the Mariners 4-3 Saturday at Safeco Field.
The Athletics (39-49) can win the four-game series in Sunday's 1 p.m. game, the final game before the All-Star break. The Mariners (42-47) send Felix Hernandez (3-3, 5.04) to the mound opposite Daniel Gossett (1-3, 6.23).
Saturday's game was tied 3-3 entering the ninth inning. Earlier, Yonder Alonso hit a two-run homer early for Oakland. Jean Segura and Ben Gamel had run-scoring hits for Seattle. Marcus Semien gave Oakland a 3-2 lead with a fifth-inning homer, and the Mariners tied it in the bottom of the inning on Jarrod Dyson's homer.
Diaz, who has suffered his share of rough outings, gave up an infield single to Rajai Davis, who later stole second base. With two outs, Diaz intentionally walked Alonso. Then, Healy stroked a ground-rule double to deep right field, plating Davis as Oakland went ahead 4-3.
Santiago Casilla quickly got two outs in the bottom of the inning, but Mitch Haniger reached on a two-out double. Casillas got Dyson to fly out to left field to end the game.
Diaz fell to 2-4 with a 3.63 ERA.
Seattle's Andrew Moore, the ex-OSU pitcher, gave up six hits and three runs in six innings.
